Display images from assets folder in Flutter

• Create a folder in the root directory of your app called assets. Inside, place your image i.e. this_is_an_image.png. The relative path will be assets\this_is_an_image.png

• In pubspec.yaml, under flutter: entry, type the following:
  

assets:
   - assets/this_is_an_image.png

• I have been using it like that:

Container(
    decoration: BoxDecoration(
        image: const DecorationImage(
            image: AssetImage('assets\this_is_an_image.png'),
            fit: BoxFit.cover,
            ),
        ),
    ),
);
